Cole struck out six. Shaw's single was part of a four-run fourth for the Blue Knights, who play Fairfield Warde in a semifinal Tuesday at Muzzy Field in Bristol.

"At this time of year in the state tournament, every win is a big win," Southington coach Charlie Lembo said. "Manchester did a great job today; they played good defense. Our guys, the second time through the lineup, started swinging the bats."

Southington reached its fourth straight semifinal; the Blue Knights lost in the 2011 and 2013 finals. They will play No. 15 Fairfield Warde on Tuesday at Muzzy Field in Bristol.

Moskey (8-2) struck out seven and Ty Schuler had two hits and two RBI for H-K, which will play No. 2 Plainfield in a semifinal Tuesday at Beehive Field in New Britain. Clay Felice had a double for East Catholic (15-8).
